Recently I’ve been messing around with HDMI cables since I’ve been watching Netflix movies and TV shows on my TV that isn’t smart.
I have noticed that the cables can discern if they’re plugged in or not. If I plug in the cable with my computer off, the TV says “No signal”, and if I disconnect the cable, the TV says “Verify cable connection”. How do the device knows the difference?
I apologize for my poor English.

A HDMI cable has something like 8 or 10 pairs of wires, 16 or 20 total connection points. Each one of those connection points runs a certain type of data.
For example two of the pins on and HDMI cord may be to run a bit of low voltage power through to let the device know that it’s connected and ready to go
